Does anyone have discrete input codes for a Proscan TV? I do not have the model number. The tv has 4 video inputs, 2 VGA inputs, and 1 input labeled COMP used for the DVD. Ch + does not go directly to the tv tuner, it only toggles through the inputs. If no one has discrete codes, does anyone know how to go to the input that is needed, other than just a input button that togggles though the inputs?
